On average in Switzerland 50% fail on the first attempt

Intro: Check out my feedback for my instructor, Peter Zwyer. The exam was scheduled at 14:00. I asked Peter to make a warm-up session before, so we met at about 13:00 to drive a bit, then have a rest, then decide go/nogo for exam. So: "go". I did not know what to expect from this exam, just was warried, because on average in Switzerland 50% fail on the first attempt and I do badly need driving license nowadays. We were driving around Zug, Steinhausen, highway, did parking. I made one relatively bad mistake (turned from main road to the road between houses, and there were 3 roads coming from the right where I should yield priority, but the first road was just a few meters after the turn and I somehow missed it). Highway -- fine, despite slightly "deviating", or "steering away" when looking for blind spots, basically it should "go away" after getting more driving experience. Parking, just driving around, emergency stop. Total time was about 45-ish minutes + debriefing and paperwork. I'm glad that my instructor did good job teaching me and everything went fine from the first attempt.
